Frequently Asked Questions

What is a Unicode code point?

A code point is the unique number assigned to each character in Unicode, written as U+XXXX in hexadecimal. For example, 'A' is U+0041, '😀' is U+1F600.

What is the difference between a code point and a byte?

A code point is an abstract character number (U+1F600); bytes are how it is stored. In UTF-8, U+1F600 becomes the 4 bytes F0 9F 98 80. One character can therefore be 1-4 bytes.

Why do some emoji count as two characters in JavaScript?

JavaScript strings use UTF-16, where code points above U+FFFF are stored as a surrogate pair of two 16-bit units. '😀'.length is 2 even though it is one code point - use [...str].length to count code points.
